Abstract RU 2345081 C2

FIELD: chemistry.

SUBSTANCE: invention relates to 2,2'-di(3,4-alkylenedioxythiophene)s of general formula (I) , where A, R and x have given in description values, which are intended for obtaining electroconducting or semiconducting compounds and valuable semi-products for π-conjugated polymers. Also described is method of their obtaining and method of obtaining poly(3,4-alkylenedioxythophene)s based on them. Claimed method allows to obtain novel 2,2'-di(3,4-alkylenedioxythiophene)s by simplified techniques and extend possibilities of their application.

EFFECT: obtaining agents by simplified techniques and extension of possibilities of their application.
